total area = 18.28 in.^2

perimeter = 16.28 cm

Step-by-step explanation:

Area:

The total area of the figure is the sim of the area of the rectangle and the area of the semicircle.

total area = LW + (1/2)(pi)r^2

total area = (4 in.)(3 in.) + (1/2)(3.14)(2 in.)^2

total area = 12 in.^2 + 6.28 in.^2

total area = 18.28 in.^2

Perimeter:

The perimeter of the figure is the sum of the lengths of the left side, bottom side, and right side of the rectangle and the circumference of the half circle.

perimeter = 3 cm + 4 cm + 3 cm + (1/2)(pi)d

perimeter = 10 + (1/2)(3.14)(4 cm)

perimeter = 10 + 6.28 cm

perimeter = 16.28 cm
